Metal-organic frameworks(MOFs) and covalent organic frameworks(COFs) with highly ordered porous structure, tunable bandgap, large specific surface area and structural diversity, provide an appealing platform for the development of stimulus response, sensing, imaging and optoelectronics. Among various tuning methods, pressure engineering using the diamond anvil cell is a highly powerful in-situ technique, which can efficiently modulate the structural and optical properties of MOFs/*** is beyond the realization of traditional chemical methods. This review outlines the research progress in the experimentoriented discovery of new phases or unique properties under high pressure, including phase transition, abnormal compression,photoluminescence(PL) discoloration and enhancement. Notably, the improvement of PL quantum yield in MOFs could be achieved by pressure-treated engineering and hydrogen-bonding cooperativity effect. We also propose and establish the relationship between structure and optical properties under high pressure. Finally, the challenge and outlook of the current fields are summarized. We hope that this review will supply guidance for comprehending the development of high-pressure MOF/COF-related research fields, and offer novel strategies for designing more high-performance MOF/COF materials to ultimately expand their applications.

Cl- ions accelerating interface charge transfer in a Si/In2S3 Faradaic junction photocathode for solar seawater splitting

引用

Science China Chemistry 2024年第9期67卷 2923-2929页

作者： jun Luo Ruotong Bao Hongzheng Dong Ye Fu Dongjian Jiang bo Wang Yuzhan Zheng Qiong Wang Wenjun Luo Zhigang zou Eco-materials and Renewable Energy Research Center (ERERC) Jiangsu Key Laboratory for Nano Technology National Laboratory of Solid State Microstructures College of Engineering and Applied Sciences Nanjing University National Laboratory of Solid State Microstructures and Department of Physics Nanjing University

Photoelectrocatalytic seawater splitting is a promising low-cost method to produce green hydrogen in a large scale. The effects of Cl-ions in seawater on the performance of a photoanode have been reported in previous studies. However, few researches have been done on the roles of Cl-ions in a photocathode. Herein, for the first time, we find that Cl-ions in the electrolyte improve the photocurrent of a Si/In2S3photocathode by 50% at-0.6 VRHE. An in-situ X-ray photoelectron spectroscopy（XPS） characterization combined with the time-of-flight secondary-ion mass spectrometry by simulating photoelectrochemical conditions was used to investigate the interface charge transfer mechanism. The results suggest that there is an In2+3S3–x（OH）2xlayer on the surface of In2S3in the phosphate buffer solution（PBS） electrolyte, which plays a role as an interface charge transfer mediator in the Si/In2S3photocathode. The In2+3S3–x（OH）2xsurface layer becomes In2+3S3–x（Cl）2xin the PBS electrolyte with NaCl and accelerates the charge transfer rate at the In2S3/electrolyte interface. These results offer a new concept of regulating interface charge transfer mediator to enhance the performance of photoelectrocatalytic seawater splitting for hydrogen production.
